摘　　要：针对1,2,3,4-丁烷四羧酸(BTCA)防皱整理棉织物强力损失的问题,采用在整理液中加入糖类添加剂的方法,对棉织物的防皱性能进行改善;通过分子尺寸计算和傅里叶转换红外光谱测试,分析其作用机制。结果表明:葡萄糖、蔗糖和麦芽糖均可进一步提高BTCA整理织物的折皱回复角,同时降低织物的强力损失;葡萄糖对折皱回复角的提高作用最大,其质量浓度为10.0 g/L时,折皱回复角达到最大值260°,比不加葡萄糖的增加了22°;但将白度考虑在内,选择麦芽糖为最佳糖类添加剂,添加剂分子半径越小,越易扩散进入纤维内部,对折皱回复角提高作用越大;折皱回复角提高的原因是在不同BTCA分子之间建立了共价桥接。Due to the strength loss of cotton fabrics treated with 1,2,3,4-butanetetracarboxylic acid（ BTCA）,different carbohydrate additives were added into the finishing bath to improve the antiwrinkle properties of treated fabrics. The action mechanism was analyzed by molecular size calculation and Fourier transform infrared spectroscopy（ FT-IR）. The results show that glucose,sucrose and maltose can further increase the wrinkle recovery angle（ WRA） of the treated fabric and reduce the fabric strength loss. Glucose shows the greatest effect on WRA increasing,and WRA of the treated fabrics reaches the maximum value of 260° when the dosage is 10. 0 g/L,increasing by 22° compared with those without glucose. However,taking the whiteness index into consideration,maltose was selected as the most appropriate carbohydrate addictive here. According to the calculation of connolly solvent excluded volume and radius of carbohydrate additives and based on the diffusion equation,it can be concluded that the molecule with smaller molecular radius can spread into the deeper section of the fiber and the effect on WRA improvement is more significant. FT-IR test shows that the mechanism of WRA enhancement is because of the covalent bridging through glucose between different BTCA molecules just grafted onto the fibers.
